and exact description, such as will enable others skilled in the art towhich it appertains to make anduse the same, reference "being had to theaccompanying drawings, forming part of this specification, in whichFigure 1 is an elevation artly in section of a lateral motion truck 5owing the preferred form of my invention applied thereto. Fig. 2 is a'plan view of the preferred form of my invention. Fig. 3 is an elevationin section on line 33 of Fig. 2. Fig. 1s a plan view of a modified formof my invention. Fig. 5 is an elevational section on line 5-5 of Fig. 4.Fig. 6 is a corresponding elevation in section of a second modificationof my invention. Fig. 7 is a detail partly in section of the secondmodification. Fig. 8 is an elevation of a portion of car structureillustrating theuse of my invention as a means for supporting the car onthe trucks.

The principal object of my invention is to rovide an automaticallyoperating side liearing which is adapted to be controlled by movementsof the car body and the truck to so adjust itself to coin ensate forchanges in elevation of the true relative to the car body. I

Another object of my invention is to provide such a device composed ofthe fewest number and simplest parts.

A further object of my invention is to provide such a device whereby theamount of swing or lurching of the car body on straight track ismaterially reduced.

A, still further object of my invention is to produce a device by meansof which the car body may be supported on the trucks at points on eitherside of the center, and byvirtue of the natureof said supports bemaintained horizontal, while permitting relutive displacement of theopposite sides of the truck vertically.

Other objects of my invention will be ob vious and others pointed out inthe following specification, or illustrated in the drawlngs- I As iswell understood, the function of side hearings in our construction is toprevent undue side swing or lurching of the car body relative to thetrucks. Under normal conditions, none of the weight of the car iscarried by the side bearings, but there is a clearance between the bodyside bearings and the truck side bearings which in present prescribedconstruction amounts to on either side. This construction permits of aswing of the car body of 5} at the body side bearings and anincreasingly greater swing at points higher in the body of the car. Thepurpose of this cleztrence between the side earings is to permit acertain amount of vertical movement of the trucks relative to the carbody, as when turning curves, etc., without the body and truck bearingsbind ing.

Under present construction, the amount of clearance for theaccommodation of added elevation of the trucks relative to the car bodycannot be increased without at the some time increasing the amount ofside swing of the car body on straight track. By virtue of my improvedadjustable side hearing, it is possible to reduce the amount of sideswing on straight trsch andto increase the extent of elevations].movement of the trucks relative to the car body.

As illustrated in Fig. 1', it will be seen that my invention is adaptedfor use on any. lateral motion truck, one form of which is illustratedin Fig. 1. As is well known, the feature of the lateral motion truckwhich gives it its name is the provision therein for a certain amount oflateral movement or lateral swing of the truck bolster relativeto thetruck frame. Thus when turning a curve at other than a very low speed,the centrifugal force of the car body will cause the truck bolster tohave a certain amount of movement laterally of the truck frame andcentrifugally of the curve. I

The preferred form of my invention as illustrated in Figs. 1, 2 and 3comprise an anchor plate 1 which is adapted to be secured to the archbar 2 or other portion ofthe truck frame, and is provided with avertically slotted. or apertured portion 4. A

base member 5, which is adapted to be mounted upon the truck bolster 6,is provided with an inclined bearing face 7 disposed with its highestportion toward the outer end of the bolster. -At the ends of themclined. surince the base memberis presided with olding flanges 8whicijjjereadapted.

to retain on the inclined surface between struction is such that whenthe base member 5 is moyed inwardly oii the truck-frame, by virtue ofthe coaction of the sloping bean ing portions of the base member and theshift-able member 9, the latter will be raised relativeto the bolster,and as the base memher is moved outwardly of the truck frame theshiftable member 9 will ride down the sloping portion 7 and. be loweredrelative to the bolster.

As illustrated in Fig. 1, it- Will' be seen that this shifting of thebase members o is accomplished'by the lateral movement of the bolster 6relative to the truck frame, and'thatduring such movement of the bolster6, the shiftable members 9 are retained against any lateral movement Asa result of this operation, when the car is rounding a curve at aconsiderable speed, andthe bolster shifted laterally of the truck frameby the centrifugal force, the shiftable member of the bearing which ison the outside of the curve will be lowered relative to the twister,while the opposite shiitable member will be raised,

and by this means the superelevation of the outer rail on the curve willbe compensated so as to maintain the car body in its normal horizontalposition. By virtue of this improved side bearing constructed in theprpportions illustrated, it is possible to dispose the truck and bodybearings so that there is but iv clearance between them as contrastedwith the =3 obtaining under present constructions. By virtue of thisdisposal, it is readily apparent that the side swing of the car body onstraight track at the side bearing is reduced from 1 1- to it". At-thesame time, the amount of clearance to compensate vt'or difference inelevation of the rails is increased t'rom g to 1%.

In the modified t'orm illustrated in Figs. d and 5, it will be seen thatinstead of employing sloping faces on the base and the shiftablemembers, the two are pivotally connected by links 12, by virtue of whichconstruction lateral movement of the base member 5 operates to raise orlower the shift-able member 9 in the same "fashion and under the sameconditions as described with reference to the preferred form. 5

In the modification shown iii Figs. 6 and '2', the base member 5 isprovided with a notches the incline of the base member 5*.

ing member of the car or body bolster is hearing roller 14 and theshift-able member v 9 is provided with an adjustable Wedge block 15whose normal position in the shiftable member may be varied relative tothe beering roller 14. fits illustrated in said figures,

the wedge block 15 is removable through the lower portion of shittablemember 9, and is retained against lateral movement therein byinter-engaging serrations or teeth 16 formed on the inner walls of theshittable member 9 and the ends of the Wedge block 15. In this form, thebearing roller 14 rolls up and" In the form illustrated in Figs. d and9,.

the shiftable member 9 is mounted upon the.

base member 5 and is provided with the arcuate sloping; bearing member9*. An e2 tension spring 25 seated against'a stop 2% tends to move theshittable member 9* The bearadapted to cooperate with the top of thebearing member 9 and the body portion of the car also carries thebracket 21 in which is mounted the bearing roller 22. Roller 22cooperates with'the sloping arcuate face 9" of the member 9 in suchmanner that as the side of the truck is elevated toward the car body,the bearing member 9 will be forcedinward against the action of thespring 25 and down the sloping bearing member 5. In this manner, addedclearance will. be pro vided to compensate for the elevation of theside'- of the truck relative to the car body. Coincident with suchoperation, the corre sponding bcaring'on the other side of thetruclnwhich side of the truck it will be understood has been loweredrelative to the car body, will have been pushed up the sloping basemember 5-by its spring 25 to compensate for-the lowering of that side ofthe truck relative to the car body.

It will be obvious that on going-into a curve the centrifugal force ofthe car body will tend to tip it toward the outside of the curve, evenbefore the corresponding side of the truck has been raised by theelevation of the outside rail. This tipping ot' the car body willoperate to lower the side bearing in the manner just described toprovide a certain amount of clearance to accommodate the first elevationof the side of the truck.

It is obvious that because oi the automatic operation of the structuresab ve described, my invention is adapted to be used as a means forsupporting the car body on the trucks at either side of the trucks. InFig. 10 is illustrated such an application of my invention. The bodybolster 26 is shown with its bearing members 27 resting directly uponthe shiftable members 9 of my desm-sew vice, the entire weight of thecar being supported near the endsof the truck bolster, and themember 28corresponding to-a center bearing acting merely as a pivot between thebolsters and not a supporting member. liy virtue of this construction,it is possible to dispensevwi'th the heavy forms of truck bolsters no'wnecessary, as the weight is supported near the ends of the truck and notin the center. With the car body thus supported directly on theshiftable members 9,

w it. will be seen that the centrifugal force actingnpon the car bodywill move the lateral motion member 6 toward the outer side of thecurve, Thismovement of the lateral motion member will move the basemembers 5 so that the shiftable member 9 on the outside otthe curve islowered while that on the insideof the curve will be raised. In thisfashion, the car, body will be maintained at a constant level while theside of the truck is permitted to rise on'the elevated rail.

I am aware that further modifications of my invention may be devised andthat it maybe disposed so that its operation is dependent upon portionsof the car other than the truck bolster.

I am also aware that it is applicable to forms of truck in carconstruction other than that illustrated, and I. therefore, do

not intend either that my invention shall;

be limited in scope to the specific forms or to the particularapplications shown and described, but that it be construed to comprehendall obvious modifications and ap plications.
